Answer:
53 54 55
Step-by-step explanation:
Consecutive Integers are integers that go one after the other unless explained otherwise, so 53, 54 and 55 add up to 162.
Answer:
This above options makes the expression true.
- The negatives above can be distributed up as well, which happened in A.
- In E, when the negatives inside the bracket cancels out, the negative outside the brackets multiplies and makes the expression true.
- In B the expression turns positive, thus false same happens with C and D
Answer:
4a + 4
Step-by-step explanation:
f(x) = x² + 2
f(a) = a² + 2
f(a+2) = (a+2)² + 2
f(a+2) − f(a) = (a+2)² + 2 − (a² + 2)
f(a+2) − f(a) = a² + 4a + 4 + 2 − a² − 2
f(a+2) − f(a) = 4a + 4
a = adult ticket price
s = student ticket price
---
7a + 2s = 87
---
4a + 6s = 74
4a = 74 - 6s
a = 74/4 - (6/4)s
a = 37/2 - (3/2)s
---
7a + 2s = 87
7(37/2 - (3/2)s) + 2s = 87
7(37/2) - 7(3/2)s + 2s = 87
(259/2) - (21/2)s + 2s = 87
(21/2)s - 2s = (259/2) - 87
(21/2)s - (4/2)s = 259/2 - 174/2
(17/2)s = 85/2
---
s = 85/2(2/17)
s = 85/17
---
Answer:
s = $5
a = $11
